Bluetooth and Wifi Unlocker is an Android app that does just what it sounds like: removes the need to type in a passcode or phrase or gesture whenever you're connected to either a familiar Wi-Fi network, or a particular Bluetooth device. Adding Bluetooth lets you keep your phone accessible when you're streaming music at home, to headphones, when you have your Fitbit attached, or when you're in your Bluetooth-enabled car (only while you're stationary, we hope). The passcode goes back on the moment your phone is out of range of your chosen device, so would-be snoops are out of luck if you're not near your phone.

Bluetooth and Wifi Unlocker is available as a free app, with tough limits on the number of Wi-Fi networks and Bluetooth devices and preferences. The $3 paid version removes those barriers.
